CROSS-BEARER.

Specification of Letters Patent.

Patented Jan. 9, 1906.

Application filed July 18, 1905- Serial N0. 270,226-

To all whom it may concern:

Be it known that I, ALLEN E. OSTRANDER, a citizen of the United States, residing at Paterson, Passaic county, New Jersey, have invented a certain new and useful Improvement in Cross-Bearers, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which Figure 1 is a view of a cross-bearer partly in plan and partly in section. Fig. 2 is a transverse sectional view through the center sills and side sills, the cross-bearer being illustrated in elevation. Fig. 3 is a perspective view of one end of the cross-bearer. Fig. 4 is a perspective view of a portion of the strut, and Fig. 5 is a perspective View of one of the tying members.

This invention relates to cross-bearers for railway-cars; and one of the objects is to provide a trussed structure capable of sustaining a maximum weight and resisting strains without requiring an unusual amount of bracing.

Another object of the invention is to provide a trussed structure which may be conveniently applied to underframing of cars.

Other objects and advantages, as well as the novel details of construction, will be more specifically referred to hereinafter, it being understood that minor changes in the form, proportion, and minor details of construction may be resorted to without departing from the spirit of the invention or sacrificing any of the advantages thereof.

In the form illustrated, 1 designates the.

center-sill members, having vertical webs whose upper edges are outwardly turned to form integral flanges 2. These integral flanges 2 serve as top chords of the girders of which the center-sill members consist, and the bottom chord members comprise angles 3 and 4, the vertical flanges of which are riveted to the webs of the center-sill members with the horizontal flanges disposed in opposite directions.

The side flanges of this filler Interposed between the 0611".

are secured to the webs of the center-sill members, which flanges project in a direction opposite to the flanges 7 of the angles 8, which angles are secured to the face of the filler 5 and to the webs of the center-sill members.

9 designates cover-plates which rest upon the tops of the upper flanges of the centersill members, and 10 designates the tension member of the truss, which extends from side sill to side sill, said tension member projecting downwardly from the edges of the center sill and carries a gusset 11, one at each end, which gussets are provided with portions parallel with the portions 12 of the gussets 13, which are secured to the ends of the channel compression member 14. This channel compression member extends beneath the center sill and is secured to the angles 3 and 4 and to the filler 5, which serves the purpose of a strut. The upwardly-projecting ends of the compression member 14 are secured to the respective ends of the tension member 9 through the gussets 11 and 13 by means of rivets, which pass through said gussets and through the bottom flange 15 of the channel side sills 16, Whose flanges project inwardly. The u per inwardly-projecting flange of each side si 1 is on a line with the top of the tension member, so that the transverse floor-strips 17 may extend from side sill to side sill. The strips 17 rest upon the floor-strips 18, which in turn are supported upon the horizontal flanges 19 of the diagonal braces 20, which are secured to the tension members and webs of the side sills. These diagonal braces are provided with longitudinal ribs 21 to add strength and rigidity to the truss.

The tying members 22 (illustrated in detail in Fig. 5) are secured to the webs of the center-sill members and to the downwardly-projecting flanges of the channel compression member, so as to tie in the channel to the center sill and assist in resisting strains to which the truss will be subjected.

It will be apparent that by utilizing a cross-bearer of the construction heretofore described the truss will be able to sustain a maximum load and to equally distribute the strains to the parts of the car best adapted to resist them. The member designated by the numeral 5, together with the center sills, serves as a strut, and this member 5 preferably extends upwardly the entire height of the center sill, being secured at top and bottom to the tension and compression members, respectively.

Having thus described my invention, what I claim as new, and desire to secure by Let ters Patent, is

1. A cross-bearer comprising a continuous flat top member, a continuous channel bottom member, a center sill interposed between the top and bottom member, and braces 22 connected to the center sill and channel; substantially as described.

2. A cross-bearer comprising a flat top member, a channel bottom member, a strut interposed between the top and bottom members, side sills to which the top and bottom members are secured, braces connecting the top member and side sills, and braces connecting the strutand channel bottom member; substantially as described.

3. A cross-bearer comprising a flat top member, a channel bottom member, a center si-ll interposed between the top and bottom members, terminally connecting plates 11 and 13 carried by the top and bottom members, respectively, and side sills to which said connecting-plates are secured; substantially as described.

4. In a railway-car, the combination with the center sill and side sills thereof, of a tension member passing over the top of the center sill, a compression member passing below the center sill and connecting-plates 11 and 13 terminally carried by the tension and compression members and beneath the side sills to which they are secured; substantially as described.

5. In a railway-car, the combination with a'center sill and side sills, of a flat plate tension member passing over the top of the center sill and beneath the side sills, a continuous channel compression member passing beneath the center sill and secured to the bottoms of the side sills, said channel having depending flanges; substantially as described.

6. In a railway-car, the combination with a center sill and side sills, of a flat plate tension member passing over the top of the center sill and beneath the side sills, a continuous channel compression member passing beneath the center sill and secured to the bottoms of the side sills, said channel having depending flanges, and braces connected to the channel compression member and the center sill; substantially as described.

7. In a railway-car, the combination with a center sill and side sills, of a flat plate tension member passing over the top of the center sill and beneath the side sills, a continuous channel compression member passing beneath the center sill and secured to the bottoms of the side sills, said channel having depending flanges, and braces connected to the top tension member and the upper portion of the side sills; substantially as described.

8. In a railway-car, the combination with a center sill and side sills, of a flat plate tension member passing over the top of the center sill and beneath the side sills, a continuous channel compression member passing beneath the center sill and secured to the bottoms of the side sills, said channel having depending flanges, braces connected to the channel compression member and to the center sill, and braces'connected to the top tension member and the upper portion of the side sills; substantially as described.

9. In a railway-car, the combination with the channel center-sill members having outwardly-turned flanges, a diaphragm 5 interposed between the channel center-sill members, angles connected to the diaphragm and to the center-sill members, a flat plate tension member passing over the center sill and extending from side sill to side sill, a channel compression member passing beneath the center sill and extending from side sill to side sill, braces connected to the channel compression member and to the center sill, braces connected to the tension member and to the upper portion of the side sills, and connecting-plates carried by the ends of the compression and tension members and secured to the bottoms of the respective side sills; substantially as described.

In testimony whereof I hereunto aflix my signature, in the presence of two witnesses, this 11th day of July, 1905.
